Ceiling Flush Mounted PIR Occupancy Switch in White, Presence

This Danlers ceiling flush passive infra-red occupancy switch (PIR) can be flush mounted into suspended and plasterboard ceilings.

It includes a 2 metre connecting flex to make installation quicker and easier.

These neat and unobtrusive models are ideal for flush mounting through suspended or plasterboard ceilings. They have a 2m cable, for quick installation.

• These PIR switches incorporate a passive infrared quad sensor to detect movement of a warm body within their detection zone and a photocell to monitor the ambient light level.
• Upon detecting movement, if the ambient light is dark enough, the PIR switch will turn the load on.
• The ambient threshold can be set by the user to between approximately 100 lux and infinite lux (photocell inactive) via the LUX adjuster.
• If no more movement is detected within a pre-selected time, then the PIR switch will turn the load off.
• This time lag can be set via the TIME adjuster to 10 seconds, 20s, 40s, 1 minute 15 seconds, 2m30s, 5m, 10m, 20m or 40 minutes.
